Hi,

now I need you help with my Omega Ref. 2627 Calendar.

I am asking, because there are many redials out there and my dial is kind of clean.
On the other side, the movement looks good, too (no water damage, no grinding marks inside).
And the genuine crown looks also well preserved.

So, I need your expertise:

Thanks in advance,
Peter

Looks very good to me. I would say all original ( except for blue seconds hand).
The 355 movement looks very clean and can be correct for this ref according to this older OF thread.
Nice watch!!

Thank you so far.
Yeah, saw the blue second hand only on the gold versions, so possibly replaced.

I actually like the blue seconds hand I wouldn’t bother replacing it. And maybe I’m wrong could be orig? The experts will know better than I. Lovely watch!

Looks great!

I don't like date watches....apart from when they have the date at 6 and so I really like collecting the 2627 and 2757 references.

Here's one of mine

To complete this topic:

Found another Seamaster Automatic Calendar Ref. 2627 with bright dial and blued second hand:

And it seems, that the watch has the genuine crystal, if this is an Omega sign on it:

So, all looks good and I am very glad with my purchase.

Thanks all for the help! 👍👍

Best,
Peter
